Scheduled

We will be performing BIOS and Firmware upgrades on selected HPC HPE Servers to address security vulnerabilities identified.

Why:
- Potential security vulnerabilities have been identified in HPE ProLiant AMD DL/XL Servers.
- These vulnerabilities could be locally exploited to allow local disclosure of information.

Potential impact:
-There is no impact to workloads expected as the updates will be done one server at a time
- Each node will be put on a reservation and will be done when its empty of jobs and will be put back into service once completed.
